Sir I am a retired school teacher of maths n phy .science whole 40 years I was teaching only school subjects but your teaching refreshed my subject knowledge n I am able to help my grandson who is into Xi of telangana inter board your pedagogy is precise with no nonsense that doesn't mean that there is no humor all ingredients are in requisite amounts thanks for the help
At 56:20 you'll notice the short trick was correct but coincidently cuz after getting minor and cofactor he directly multiplied with the cofactor he forgot about the Transpose but coincidently transpose and cofactor are the same for that question.💤
Thankyou so much sir aise lecture se sare doubt clear ho gaye currently am not taking any coaching I only rely on you sir the quality of education ur providing is sooo good thankyou so much sir❤
1:09:27 answer is : P = 3000, Q = 1000, R = 2000 Let price of P,Q,R is x,y,z Equation: For A : 3x + 5y - 4z = 6000 For B : 2x - 3y + z = 5000 For C : -x +4y + 6z = 13000
